Face below level of toruli and scrobes golden-green, clypeus yellowish-brown, remaining parts of frons and vertex metallic bluish-green. Thoracic dorsum metallic bluish-green. Legs with fore and mid coxae yellowish-brown, hind coxa metallic bluish-green with anterior and apical parts yellowish-brown; trochanters, femora and tibiae yellowish-brown; T1–3 yellowish-brown, T4 brown. Petiole black. Gaster with Gt 1 metallic bluish-purple, Gt2-5 golden-purple, Gt6 metallic green, Gt 7 with basal half metallic green and apical half black; gonoplac dark brown.

Antenna with distinct constriction between C1 and C2. Face below level of toruli with weak reticulation, clypeus smooth, frons rugose, antennal scrobes with weak reticulation; with genal carina. Vertex with strong reticulation outside ocellar triangle, with wrinkled sculpture inside ocellar triangle; with a carina between posterior ocelli in posterior part.

Mesoscutum with strong reticulation, meshes isodiametric on sidelobes, elongate on midlobe, midlobe with parts close to notauli rugose; midlobe with a median groove, with 24 scattered setae on rugose part close to notauli. Mesoscutellum with median part with weak reticulation and shiny, meshes elongate, lateral parts rugose and covered with setae; outer margins of submedian grooves indistinct. Dorsellum with strong reticulation, with median carina. Propodeum a median carina that is concave and expands gradually towards posterior part; with strong reticulation; callus with three setae. Fore and hind coxae with strong reticulation, mid coxa with weak reticulation. Fore wing with five setae on dorsal surface of submarginal vein; speculum open below; costal setal row unbroken.

Petiole very short, just a narrow band. Gaster very elongate; medio-basal Gt 1 with a transverse carina dorsally; tergites with very strong and large-meshed reticulation.
